ROLSEN RL-32L1002U
General recommendations for TV LCD LED repair
It is advisable to start repairing the ROLSEN RL-32L1002U TV with a careful external examination of both internal and external elements. Often, based on external signs and the nature of damage to elements, it becomes possible to draw some conclusions and determine a further algorithm for searching for a defect before taking the necessary measurements at control points. If ring cracks are found in the soldering of the element terminals or broken connecting tracks, swollen capacitors or charred resistors - all this may be characteristic signs of the causes or consequences of an already known typical malfunction.
In the case when the RL-32L1002U does not turn on, does not respond to the remote control and front panel buttons, does not blink lights and does not show any signs of operability, the PBB1-C2Q093-92630 K-75L1 465R1014SDJB power supply module is probably faulty in this case. If it is working properly with such manifestations, it is necessary to check the processor power regulator (converter) on the motherboard. When repairing a power supply, it is advisable to start diagnostics with checking the mains fuse and electrolytic capacitors of the filters of the converter's secondary rectifiers. In the event of a break in the fuse, the cause should be sought in the power semiconductor elements of the pulse converter of the main power supply unit. First of all, it is necessary to check the diodes of the mains voltage rectifier bridge and the power switch (keys) of the F3NK80Z, SW10N65 converter.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (SMPS) it does not fail by itself without reasons that should be looked for by checking other elements of the primary circuit - electrolytic capacitors, PWM controller 2pcs 6pin 73B51 A, , which can only be checked by replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If when you turn on the ROLSEN RL-32L1002U there is no image, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the LED circuit of the T315XW06 V.3 panel backlight, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the common power supply.
Often, in the absence of backlighting, disassembly of the panel is required. It is necessary to check the serviceability of the LED transitions, as well as the reliability of the contact connections in the lines and connectors.
To identify an open circuit in the LED lines without disassembling the panel, a current source is required. It is impossible to open the junctions connected in series with a simple multimeter; a voltage of several tens of volts is required.
Repair of the MST6M48 / MST6M182-T8B 471-01A4-64801G motherboard must begin with diagnosing and checking all linear stabilizers or power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM.
Attention! Users and owners of RL-32L1002U TVs who do not have the appropriate qualifications, knowledge and experience are strongly discouraged from attempting to repair themselves in order to avoid negative consequences that may lead to complete non-repairability of the device.

To reduce the backlight current in LED drivers with a MAX16814 PWM controller (TSSOP20 MAX16814B), the total resistance of the resistors from pin 10 (SETI) to the package must be proportionally increased. The maximum current in each of the four channels (in milliamperes) for the resistance Rseti (in kilo-ohms) is determined from the ratio 1500 / Rseti.

Main features of the ROLSEN RL-32L1002U device:
Installed matrix (LED-panel) T315XW06 V.3.
The LED driver T315HW07 is used to power the LEDs and is controlled by the PWM controller MAX16814, RM5103. The transformer EAC013935101M02 is installed in the LED driver converter. P1825AS, P3506DD keys are used as power elements of the LED driver.
The formation of the necessary supply voltages for all nodes of the ROLSEN RL-32L1002U TV is carried out by the K-75L1 power module, or its analogs using OB2273 (PWM SOT23-6) microcircuits and power switches such as F3NK80Z, SW10N65.
MainBoard - the main board (motherboard) is an MST6M182-T8B module, using M6M8-C3P284-00583 microcircuits, Spi Flash: 25Q32, PAM8610. RT8284N and others.
The CDT-3FP2I2-31 tuner provides reception of television programs and tuning to channels.
